The ability of the channel to be bent spacing between the other warp strands.

This cush ioning means may be of various forms known to those skilled in the art, but preferably it is in the nature of a relatively long stiff pile which will form a cushioning support for the window and hold it away from the woven body of the channel, as disclosed in my United States Patent No. 1,847,700, .issued March 1, 1932. The pile or other cushioningmeans preferably extends along the fabric body in three laterally spaced lines, as

plainly shown in the drawing, so that when the.

channel is erected into normal channel-shaped form (as in Fig. 5) there will be a line of padding or cushioning on the inner face of the bottom or base section of the channel and a line of pad! ding or cushioning along the inner .face of each.

side wall of the channel. t, V

The woven textile body shown in Fig. 2 may be so woven as to be readily flexible and indeed so flexible that under normal conditions. of use it might not hold 385118.136 properly. According to the present invention this woven textile body is stiffened by the application to, it of a stiffening compound or material, which'compound or material may in some instances impregnate orpartially impregnatefthe woven body.-

. The stiffening compound .or m terial'may be of any suitable form, applied'jpreferably to the back of the fabric body, in a wet or plastic condition and subsequently allowed to dry or harden. Such material is indicated at I35 in Fig.4 of the drawing. It may be any suitable knownform of sizing; oriother stiifeningi'compound; although it is preferred at present to employ a cellulosic com pound of any suitable. formula. 7 Among typical suitable formulas for thispurpose may be men tioned thosedisclosed in United States Patent No. 1,397,173,1issued Novembe'rj15, 1921; to Mitchell, or No. 1,400,196, issued December 13, 192 1, to Willkie, or .No. 13 14,333, issued February 6,

1923, to Clarke, or No.,1,521,859,'issued January 6, 1925, to Bohan. fl'hosejskilled in the art will readily understandhow tomodify the above or- ,other known cellulosic'formulaaby the addition of solvents or otherwise, to make them most suitable for use as a coating for the window" channel body. v

In a slightly different embodimen't of the invention which is preferredunder some conditions, the stiffening coating ,or material is of rubber, as, indicated at (I36 in Fig. 3 of the drawing? This may be a layer of rubber separately formedand then cemented 'or otherwiseapplied to the fabric body, or it may be applied to the woven while plasticand vulcanized thereto, or applied in any other suitable way known in the art. What is known as extruded rubber is found to be quitefsuitable.

If desired,iand particularly when, a decorative edge or finish is wanted on the channel, the edges of the channel may be provided with enlarged warp strands N0 of 'somewhat"larger diameter than the other warp strands, and these may be embraced by beads, ll'l running 'alongthe edges of the channel and clamped around'the enlarged warp strands sufliciently tightly to prevent lateral displacement and ,yet sufficiently loosely so that the beads 'may slide longitudinally along the channel so as not to interfere with the longituw dinal bending of the channel around a corner as shown in Fig. 1. Such beads may be made of any suitable sheet material such as thin sheet metal, and serve not only as a decorative finish, but also to hold the edges of the channel true and straight.

In use, the completed channel, when ready for. 5 installation, is bent up from flat form into a generally U-shaped form as shown at Fig. 5, and is inserted in a suitable groove or rabbet in a support "or frame I45, being held therein, for example, by tacks I driven at intervals through 10- ,the bottom or base portion of the channel. The 7 channel is then in proper form to support and" serve as a mounting for a window 1, which may be either fixed in the channel or slidable therein.

The form'of channel stiflened with rubber is 15 particularly advantageous because the layer of rubber on the outer face of the channel forms to some'degree a cushion between the woven channel body itselfand the surrounding support or frame.

Thestifiening material in each embodiment of 2 the invention also, has the additional advantage that it helps to hold the various fibers of the textile material inplace'a'nd is especially advantageous in'a'ssisting in holding the pile fibers; or

other fibers forming the cushioning means. This 25 is particularly true when a rubber coating is used on the fabric, but to some extent also true of other forms of coating, and due to the use of this stiflening coating it may be-possible at, times to omit someof the threads or strands which would 30 otherwise be required in'order to hold thepile strands in place. i a

The term non-metallic" as applied to the stiflening material in this specification and the accompanying claim} is not intended to exclude 5 finely ground-up particles of metal such asare used, for example, ingalur'ninum paint, bronze paint, andthe like. Obviously such ground-up particles of metal couid'be added to the'stiifening;
